As illustrated in FIGS. 1A and 1B, an information processing system 1 according to the present embodiment includes a server apparatus 10, a client terminal 12, and an imaging apparatus 14. The server apparatus 10 and the client terminal 12 are coupled via a network 16 such as a wireless LAN. The imaging apparatus 14 and the client terminal 12 are coupled via a network 18 such as a wireless LAN. The client terminal 12 is coupled to the server apparatus 10 or the imaging apparatus 14 by switching between the network 16 or 18 acting as a coupling destination.

FIG. 1A illustrates a state in which the client terminal 12 switches the coupling destination to the network 16 such that the client terminal 12 is coupled to the server apparatus 10. FIG. 1B illustrates a state in which the client terminal 12 switches the coupling destination to the network 18 such that the client terminal 12 is coupled to the imaging apparatus 14. For example, FIG. 1B illustrates an example of a communication system that allows the client terminal 12 and the imaging apparatus 14 to directly communicate with each other on a one-to-one basis, such as Wi-Fi Direct (registered trademark).

The server apparatus 10 manages firmware for the imaging apparatus 14. The server apparatus 10 provides firmware information to the client terminal 12, based on a request from the client terminal 12. Additionally, the server apparatus 10 enables firmware information to be downloaded by the client terminal 12, based on a request from the client terminal 12.

Software Configuration

The following describes process blocks of the client terminal 12. Process blocks of the server apparatus 10 and the imaging apparatus 14 are similar to those of existing process blocks, and therefore the description thereof is omitted.

The client terminal 12 according to the present embodiment is implemented by process blocks as illustrated in FIG. 5, for example. FIG. 5 is a block diagram of an example of a client terminal according to an embodiment. The client terminal 12 executes programs such as applications for the imaging apparatus 14 (hereinafter called an “imaging apparatus application”) to implement a communication processing unit 20, a coupling destination switching unit 22, a latest firmware version information acquisition unit 24, a firmware download control unit 26, a firmware update control unit 28, an imaging apparatus battery remaining level monitoring unit 30, a firmware version information storage 32, and a firmware storage 34.

The communication processing unit 20 communicates with the server apparatus 10 or the imaging apparatus 14 via the coupling destination network 16 or 18. The coupling destination switching unit 22 switches the coupling destination network 16 or 18 by a user operation. Note that the coupling destination switching unit 22 may automatically switch the coupling destination insofar as the coupling destination switching unit 22 is enabled to switch the coupling destination network 16 or 18 according to an instruction from the imaging apparatus 14 application.

The latest firmware version information acquisition unit 24 acquires version information of the latest firmware from the server apparatus 10 and reports version information of the latest firmware to the firmware download control unit 26. The firmware download control unit 26 determines whether to download the firmware based on the reported latest firmware version information and on the firmware version information, to be described later, stored in the firmware version information storage 32.

Details of Process

The following describes details of the process of the information processing system 1 according to the present embodiment.

Process Outline in Client Terminal

The client terminal 12 according to the present embodiment performs a firmware downloading process and a firmware updating process according to a procedure as illustrated in FIG. 6, for example. FIG. 6 is a flowchart of an example illustrating a process outline with respect to the client terminal according to the present embodiment. In step S11, the client terminal 12 activates the imaging apparatus 14 application, for example, by receiving a user operation.

In step S12, the client terminal 12 determines whether the client terminal 12 is communicably coupled to the server apparatus 10. When the client terminal 12 is communicably coupled to the server apparatus 10, the client terminal 12 performs the firmware downloading process in step S13. Details of the firmware downloading process in step S13 will be described later.

When the client terminal 12 is not communicably coupled to the server apparatus 10, the client terminal 12 determines whether the client terminal 12 is communicably coupled to the imaging apparatus 14. When the client terminal 12 is communicably coupled to the imaging apparatus 14, the client terminal 12 performs the firmware updating process in step S15. Details of the firmware updating process in step S15 will be described later.

When the client terminal 12 is not communicably coupled to the imaging apparatus 14, the client terminal 12 performs various processes in step S16. The various processes in step S16 are processes other than the firmware downloading process and the firmware updating process executed by the imaging apparatus 14 application in the client terminal 12. Further, the client terminal 12 performs various processes in step S16 after the execution of the firmware downloading process in step S13 and the firmware updating process in step S15. Note that the process of the flowchart of FIG. 6 may be performed every predetermined time (e.g., one hour) in addition to when the application is activated.

As illustrated in the flow chart of FIG. 6, when the imaging apparatus 14 application is started, the client terminal 12 performs a process in accordance with the coupling destination depending on whether the coupling destination is the network 16 or the network 18. Specifically, the client terminal 12 performs a firmware downloading process with the server apparatus 10, when the network 16 capable of communicating with the server apparatus 10 is selected as the coupling destination. Further, when the network 18 capable of communicating with the imaging apparatus 14 is selected as the coupling destination, the client terminal 12 performs a firmware updating process with the imaging apparatus 14.

Firmware Downloading Process

FIG. 7 is a flowchart of an example of a firmware downloading process. In step S21, the latest firmware version information acquisition unit 24 of the client terminal 12 requests the server apparatus 10 for the latest firmware version information and acquires the latest firmware version information. In a case of the latest firmware version information acquisition unit 24 of the client terminal 12 being unable to acquire the latest firmware version information, the client terminal 12 terminates the firmware downloading process illustrated in FIG. 7.

Upon acquiring the latest firmware version information, the latest firmware version information acquisition unit 24 reports the acquired latest firmware version information to the firmware download control unit 26. The firmware download control unit 26 proceeds to step S22 and refers to the firmware version information stored in the firmware version information storage 32.

FIG. 8 is a configuration diagram of an example of firmware version information.

The firmware version information in FIG. 8 includes the downloaded firmware version from the server apparatus 10 and the firmware version of the most recently coupled imaging apparatus 14.

The firmware download control unit 26 compares the latest firmware version with the downloaded firmware version from the server apparatus 10 and determines whether the latest firmware has been downloaded from the server apparatus 10. When the latest firmware has already been downloaded from the server apparatus 10, the firmware download control unit 26 ends the firmware downloading process illustrated in FIG. 7. When the latest firmware has not been downloaded from the server apparatus 10, the firmware download control unit 26 proceeds to step S24.

The firmware download control unit 26 compares the latest firmware version with the latest firmware version of the most recently coupled imaging apparatus 14 and determines whether the firmware of the imaging apparatus 14 is the latest version. When the firmware of the imaging apparatus 14 is the latest version, the firmware download control unit 26 ends the firmware downloading process illustrated in FIG. 7.

When the firmware of the imaging apparatus 14 is not the latest version, the firmware download control unit 26 proceeds to step S25 and displays a download identification pop-up as illustrated in FIG. 9.

FIG. 9 is an image diagram of an example of a download identification pop-up. The download identification pop-up may enable a user to select either “Download Now” or “Not Now” with respect to the latest firmware. When the user presses “Not Now” from the pop-up in FIG. 9 (NO in step S26), the firmware download control unit 26 closes the pop-up in FIG. 9 and ends the firmware downloading process illustrated in FIG. 7. Note that the firmware download control unit 26 may receive from the user the setting of the pop-up re-display condition such as the time interval until the next display of the pop-up.

When the user presses “Download Now” from the pop-up in FIG. 9 (YES in step S26), the firmware download control unit 26 proceeds to step S27. In step S27, the firmware download control unit 26 displays a firmware update screen as illustrated in FIG. 10.

FIG. 10 is an image diagram of an example of a firmware update screen. The firmware update screen receives an instruction to “download firmware to application” from the user. When the user presses “download firmware to application”, the firmware download control unit 26 displays a firmware download in progress pop-up illustrated in FIG. 11. FIG. 11 is an image diagram of an example of a firmware download in progress pop-up.

The firmware download control unit 26 downloads the latest firmware from the server apparatus 10 and stores the downloaded latest firmware in the firmware storage 34. Upon completion of downloading the latest firmware from the server apparatus 10, the firmware download control unit 26 closes the pop-up illustrated in FIG. 11, and ends the firmware downloading process illustrated in FIG. 7.

Note that the firmware update screen, on which the “download firmware to application” button illustrated in FIG. 10 is displayed, may also be displayed, for example, when a predetermined condition is satisfied at the time of transitioning from the setting screen of FIG. 12 to the firmware update screen of FIG. 10. FIG. 12 is an image diagram of an example of a setting screen that may transition to a firmware update screen.

For example, when the firmware version of the most recently coupled imaging apparatus 14 is older than the already downloaded firmware version, the firmware download control unit 26 displays the firmware update screen of FIG. 10.

Firmware Updating Process

FIG. 13 is a flowchart of an example of a firmware updating process. In step S31, the firmware update control unit 28 of the client terminal 12 refers to the firmware version information in FIG. 8. The firmware update control unit 28 compares the downloaded firmware version with the firmware version of the most recently coupled imaging apparatus 14 to determine whether the firmware version of the most recently coupled imaging apparatus 14 is older than the downloaded firmware version.

When the firmware version of the most recently coupled imaging apparatus 14 is not older than the downloaded firmware version, the firmware update control unit 28 ends the firmware updating process illustrated in FIG. 13. When the firmware version of the most recently coupled imaging apparatus 14 is older than the downloaded firmware version, the firmware update control unit 28 proceeds to step S33, and displays the update identification pop-up illustrated in FIG. 14.

FIG. 14 is an image diagram of an example of an update identification pop-up. The update identification pop-up may enable a user to select either “Update Now” or “Not Now” with respect to the latest firmware. When the user presses “Not Now” from the pop-up in FIG. 14 (NO in step S34), the firmware update control unit 28 closes the pop-up in FIG. 14 and ends the firmware updating process illustrated in FIG. 13. Note that the firmware update control unit 28 may receive from the user the setting of the pop-up re-display condition such as the time interval until the next display of the popup.

When the user presses “update” from the pop-up in FIG. 14 (YES in step S34), the firmware update control unit 28 displays a firmware update screen as illustrated in FIG. 15.

FIG. 15 is an image diagram of an example of a firmware update screen. The firmware update screen receives an instruction to “update firmware” from the user. When the user presses “update firmware”, the firmware update control unit 28 proceeds to step S35.

In step S35, the firmware update control unit 28 checks the battery remaining level reported from the imaging apparatus battery remaining level monitoring unit 30. When the remaining battery level of the imaging apparatus 14 is equal to or greater than a predetermined level (e.g., the remaining battery level is ⅓), the firmware update control unit 28 proceeds to step S37. In step S37, the firmware update control unit 28 displays a firmware transfer in progress pop-up illustrated in FIG. 16. FIG. 16 is an image diagram of an example of a firmware transfer in progress pop-up.

The firmware update control unit 28 executes an updating process of the firmware installed in the imaging apparatus 14 by using the firmware stored in the firmware storage 34. Upon completion of the firmware updating process, the firmware update control unit 28 displays a pop-up illustrated in FIG. 17. FIG. 17 is an image diagram of an example of a pop-up prompting restart of the imaging apparatus. For example, by displaying a pop-up as illustrated in FIG. 17, the firmware update control unit 28 is enabled to prompt the user to restart the imaging apparatus 14 whose firmware update has been completed.

When the remaining battery level of the imaging apparatus 14 is not the predetermined level or greater, the firmware update control unit 28 proceeds to step S38. In step S38, the firmware update control unit 28 displays a remaining battery level warning pop-up illustrated in FIG. 18. FIG. 18 is an image diagram of an example of the imaging apparatus remaining battery level warning pop-up. For example, by displaying a pop-up as illustrated in FIG. 18, the firmware update control unit 28 is enabled to report to the user that the remaining battery level of the imaging apparatus 14 is low such that the firmware update may fail to be performed. Further, the firmware update control unit 28 may prompt the user to charge the imaging apparatus 14 using the pop-up illustrated in FIG. 18.

Note that the firmware update screen, on which the “update firmware” button illustrated in FIG. 15 is displayed, may also be displayed, for example, when a predetermined condition is satisfied at the time of transitioning from the setting screen of FIG. 12 to the firmware update screen of FIG. 15.

For example, when the firmware version of the most recently coupled imaging apparatus 14 is older than the already downloaded firmware version, the firmware download control unit 26 displays the firmware update screen of FIG. 15.

Then, after the client terminal 12 is switched to a state capable of communicating with the imaging apparatus 14, the client terminal 12 performs the firmware updating process in step S15 with the imaging apparatus 14. The imaging apparatus 14 that is designed to be communicably coupled to the client terminal 12 at the time of imaging or the like is enabled to couple to the client terminal 12 every time a user attempts to use the imaging apparatus 14 for imaging, the user may be promptly informed that firmware update is ready (available).

Hence, according to the first embodiment, the firmware installed in the imaging apparatus 14 may be updated promptly.

Example 2 Second Embodiment

The following describes a second embodiment, in which the firmware updating process is performed subsequent to the firmware downloading process. Since the second embodiment is partially similar to the first embodiment, duplicated description is appropriately omitted.

Process Outline in Client Terminal

The client terminal 12 according to the present embodiment performs a firmware downloading process and a firmware updating process according to a procedure as illustrated in FIG. 19, for example. FIG. 19 is a flowchart of an example illustrating a process outline with respect to the client terminal according to the second embodiment. In step S101, the client terminal 12 activates the imaging apparatus 14 application, for example, by receiving a user operation.

In step S102, the client terminal 102 determines whether the client terminal 12 is communicably coupled to the server apparatus 10. When the client terminal 12 is communicably coupled to the server apparatus 10, the client terminal 12 performs the firmware downloading process in step S103. The firmware downloading process in step S103 is similar to that in step S13.

In step S104, the client terminal 12 determines whether downloading of the firmware has been executed in step S103. When downloading of the firmware has not been executed in step S103, the client terminal 12 performs various processes in step S111.

When downloading of the firmware has been executed in step S103, the client terminal 12 proceeds to step S105 and displays an update identification pop-up as illustrated in FIG. 20. FIG. 20 is an image diagram of an example of the update identification pop-up displayed after downloading is completed. The update identification pop-up may enable a user to select either “Update Now” or “Not Now” with respect to the latest firmware.

When the user presses “Not Now” from the pop-up illustrated in FIG. 20 (NO in step S106), the client terminal 12 closes the pop-up illustrated in FIG. 20 and performs various processes in step S111.

When the user presses “Update Now” from the pop-up in FIG. 20 (YES in step S106), the client terminal 12 proceeds to step S107. In step S107, the client terminal 107 determines whether the client terminal 12 is communicably coupled to the imaging apparatus 14. When the client terminal 12 is communicably coupled to the imaging apparatus 14 (YES in step S107), the client terminal 12 proceeds to step S108, performs a later-described firmware updating process, and then performs various processes in step S111.

When the client terminal 12 is not communicably coupled to the server apparatus 10, the client terminal 12 proceeds to step S109 and determines whether the client terminal 12 is communicably coupled to the imaging apparatus 14. When the client terminal 12 is communicably coupled to the imaging apparatus 14, the client terminal 12 performs the firmware updating process in step S110. The firmware updating process in step S110 is similar to that in step S15. When the firmware updating process has been performed in step S110, the client terminal 12 performs various processes in step S111.

Firmware Updating Process

The firmware updating process of step S108 may be performed according to a procedure of a flowchart illustrated in FIG. 21. FIG. 21 is a flowchart of an example of a firmware updating process. Since the firmware updating process of FIG. 21 is performed after the firmware downloading process, the processes of steps S31 to S34 of the firmware updating process of FIG. 13 are omitted.

In step S121, the firmware update control unit 28 checks the battery remaining level reported from the imaging apparatus battery remaining level monitoring unit 30. When the remaining battery level of the imaging apparatus 14 is equal to or greater than a predetermined level, the firmware update control unit 28 proceeds to step S123. In step S123, the firmware update control unit 28 executes a firmware updating process similar to step S37.

When the remaining battery level of the imaging apparatus 14 is not the predetermined level or greater, the firmware update control unit 28 proceeds to step S124. In step S124, the firmware update control unit 28 displays a remaining battery level warning pop-up similar to step S38.
